Abstract

Provided are a new antenna, a bicycle including the new antenna, a display apparatus including the new antenna, and an unmanned aircraft including the new antenna. An antenna includes a first conductor, a second conductor facing the first conductor in a first direction, a third conductor, a fourth conductor, and a feeding line electromagnetically connected to the third conductor. The third conductor is located between the first conductor and the second conductor, apart from the first conductor and the second conductor, and extends in the first direction. The fourth conductor is connected to the first conductor and the second conductor and extends in the first direction. The first conductor and the second conductor are capacitively connected via the third conductor. The antenna is disposed in a bicycle component of a bicycle such that the fourth conductor faces the bicycle component.
